IMPROVEMENT IN CULTIVATORS,

Specification forming part of Letters Patent N0. 45,066, dated November l5, 1864.

To all 'whom it may concern:

Be it known that I, GEORGE D. MILLER, of Lovington, in the county of Moultrie and State of Illinois, have invented a new and Improved Cultivator and Roller Combined; and I do hereby declare the following to be a full and exact description of the same, reference being had to the accompanying drawings, making' part of this specification, in which- Figure l is a plan of my improved machine, and Fig. 2 is a vertical longitudinal section of `the same.

Similar letters ot' reference indicatercorresponding parts in the two ligures.

The objects of this invention are to facilitate the vertical and lateral adj ustment of the plows, and to employ in connection therewith a roller for crushing the clods, which roller is adapted to be raised and lowered simultaneously with the plows in a novel manner, so as to not add materially to the power required to operate said plows, all as will be hereinafter fully eX- plained.

In order that others skilled iu theart to which my invention appertaius may been abled to tully understand and use the same, I will proceed to describe its construction and operation.

In the accompanying drawings, Arepresents the several parts of the main frame of a cultivator, B the axle, and C C the carrying.- wheels. Upon this frame is mounted a swiveled frame, D D D D2, which is secured in position and adapted to turn upon a bolt, d, which passes through and connects the piece D2 and axle B, wherein it is retained by the nut d. The bolt d also secures in position and constitutes the center of movement for a segmental sheave or pulley, E, upon which is secured a bar, E', having foot rests or pieces e c at its respective ends, to enable the driver upon the seat F, by bringing his feet into requisition, to par tially rotate the pulley E,and thereby turn the frame l) D D D2, near the forward ends of the side pieces of which are pivoted the shovels G, which run adjacent to the corn when the implement is employed as a corncultivator, the

outershovels,G,beingpivoted tothesidepieces of the frame A. Movement is imparted from the pulley Eto the adjustable cultivator-frame D D D D2 through the medium of cords H H, which, being attached to the respective sides of the pulley E, pass around a pulley,I, which is mounted and rotates upon the rear end of the tongue J, the said cords H being fastened to the rear ends of the pieces D D. Little eX- ertion on the part of the driver will be required to move the cultivator frame, and thus shift the plows, inasmuch as the pulley E, in connection with the bar E', serves the purpose of alever, of which the boltdis the fulcrum andthe periphery of the pulley E the point of action, said periphery constituting a groove, so that the cord will be taken up or wound upon the pulley as fast as it is turned. The seat F'occupies such a position that the driver, when sealed upon it, will be in convenient proximity with the bar E', which may constitute a comfortable foot-rest. Said seat F is supported upon vertical armsfff, rising respectively from the tongue J and from abar, L, which issecured upon a frame, M M M. In Fig. l a portion ofthe seatF is represented as being broken awayto expose to view the pulleyE and bar E.

O is a lever joined to a transverse bar, O', the ends of which have their hearingsin brackets P P, and which is supported intermediately by a bracket, P', fastened to the tongue J. The shovels G G are connected with the bar O by cords o and links o', the cord working over pulleys q q, located at the extreme forward endsof the pieces D D of the cultivatorframe. The bar O' is provided with loops 02,

which are grooved for the reception ofthe cords o, which, passing over the loops o2 and occupying the grooves therein, are fastened thereto at the back of. the bar 0'.. The object in employing the loops o2 is to cause the connect ing cords to act upon the shovels in such manner as to elevate the same to a greater extent for a given movement of the bar O than that which would be effected it' the cords were l corn, the use of the roller being to crush the .e er R is attached.

clods which resist the action of the shovels in the act ot' plane cultivating or stirring.

In addition to the loops o2, the bar 0' is provided with a loop, o3, in connection with which is used a cord, fm, which is fastened to -the front piece, M', ofthe frame to which the roll- Hence when the 'shaft O is turned by the lever O to elevate thc shovels G G' the pivoted frame M M M is turnnd so as to describe the arc ot' a circle in a vertical plane, and this movement is of course attended with the elevation ofthe roller R, attached to the rear end of the frame. It does not require great strength to thus elevate the roller 1t, for the reason that the frame M M M operates in a manner similar to a lever, and that part of the frame to which the roller is attached may be supposed to be the short arm ofv such lever, the pivots by which the frame M M M" is supported constituting the fulcrurn and the piece M at front the point of action.

I am aware that rollers have hitherto been usedincombination with cultiventing-machines, and therefore do not claim this combination, broadly. The merit of my invention, in connection with this frame, consists in the peculiar means employed for adapting the roller to be adjusted vertically simultaneously with the adjustment of the shovel.

By reason of the peculiar manner of mounting the drivers seat F the weight of the driver is thrown directly upon the roller while the machineis in operation, and Whiletheeiiteieney` of the roller is thus increased the driver may for the moment, when it hecomes'nccessary to elevate the parts over obstacles, relieve the seat of his weight, so as to reduce the power required to depress the lever O.

The segmental pulley E, in connection with the cords H, pulley I, pivoted bar E", and foot-rests c, adapts the cultivatonframe to be adjusted with the greatest possible facility, and without subjecting the driver to inconvenience or rendering it necessary for him to assume an uncomfortable position.

The foregoing will preclude the necessity for aspecial description oi the operation of the machine.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. The swiveled frame D D D D2, in com hination with the segmental pulley E, bar or lever E', foot-pieces e e, cords H, and pulley l, the whole being arranged to operate substantially as and for the purposes herein set forth.

2. The manner herein described of employing the roller llt, so that it may be adjusted simultaneously with the plows by means ofthe lever 0.

The above specification of my improved cul.
